Metal blank carries out continuous local plastic processing, and finally accumulation forms the geometric shape of product.Since forming process is not required to
Particular manufacturing craft is wanted, i.e., the product of formable arbitrary shape eliminates the link of Mould design and manufacturing, is suitable for Thin-shell product
Single-piece or small lot production, be to conventional ones forming advantageous supplement.
Usually said progressive molding, work, tool and plate remain contact in forming process, therefore also referred to as continuously connect
Progressive molding is touched, the geometric shape of product after tool path is this passage at this time.
If the machining locus of tool is isometrical helical trajectory, i.e., tool no longer does simple motion along product shape, but edge
Movement of spinning is moved towards in former track, does periodic contact with panel surface, then is the discontinuous contact plate of helical trajectory driving
Progressive molding method.
Commonly continuously contacting with progressive molding products thickness meets the law of sines, and there are forming limit angles.In addition, along feeding side
It is larger to frictional resistance, increase external force required for sheet forming.
Relative to commonly continuously contacting with progressive molding, the discontinuous contact plate progressive molding method of helical trajectory driving by
In with plate periodic contact, between sports level direction and plate rub very little it is almost nil, and tool to plate along spiral shell
The upward active force of rotation orbit tangent can come up the lower part plate " lifting " not thinning because undressed, reduce working position plate
Expect thinning degree, to further improve the forming property of plate, mesh plate product can also be shaped.

Hand spiral criterion transformation space coordinate, initial track be it is counterclockwise, take-；Initial track be take clockwise+.
Further, with numerically-controlled machine tool or the identifiable format of dedicated progressive molding machine export isometrical helical trajectory it is progressive at
The machining locus of shape.
Further, workpiece to be added is made into plate-like structure, make workpiece to be added geometric center and forming jig it is several
What center is overlapped, and pushes down the surrounding of workpiece to be added；Forming tool under the control of numerically-controlled machine tool or dedicated progressive molding machine according to
The isometrical helical trajectory data generated carry out point-by-point progressive molding.
A kind of product is obtained using the discontinuous contact plate progressive molding method that isometrical helical trajectory described above drives
?.
Compared with prior art, the invention has the benefit that
In existing progressive molding technology, plate generated under the action of tool it is close shear-deformable, sheet thickness t after forming,
Original thickness t0And shaped side walls inclination alpha follows the law of sines, t=t substantially0sin(90°-α).When shaped side walls inclination angle is larger,
Plate thickness value will be greatly reduced after forming, or even rupture.Therefore big side wall inclination angle product is needed through the multi-pass side of design repeatedly
It is formable.
The present invention works out the machining locus of forming tool for isometrical plate screw processing track, is controlled by numerical control program
During sheet metal deformation, tool generates the active force upward along helical trajectory tangent line to plate, increases undressed region plate
To the Plastic Flow of processing part, the plate lower part plate " lifting " not thinning because undressed can be come up, reduce processing district
Locally thinning degree is formed with the production at bigger side wall inclination angle to further improve the forming property of plate to domain plate
Product.
